Worldbuilding

Definition

You're doing worldbuilding the moment your story asks the reader to accept rules reality doesn't provide — magic, the future, a vanished monarchy, an invented city. The work is to make those rules legible through friction: through what they allow and, above all, what they forbid.

What it's for

Solid worldbuilding isn't encyclopedism: it's a constraint system that produces dilemmas, costs, inequalities. The test: if you remove an element — a magical law, a border, a taboo — which scene becomes impossible? If the answer is "none," the element is decorative, not structural.

Variants by genre

• High fantasy: mythological, geographical, magical worldbuilding spread over millennia (Tolkien, Sanderson).
• Low / grimdark fantasy: fewer maps, more political regimes and muddy boots (Abercrombie, Martin).
• Hard SF: techno-physical worldbuilding that's verifiable; the author sometimes publishes the math (Kim Stanley Robinson).
• Solarpunk: worldbuilding that's political and ecological first, aesthetic second.
• Regional / Nordic crime: documentary worldbuilding — climate, languages, local administrations (Indriðason, Mankell).
• Historical / romance: sensory-oriented documentary research (clothes, smells, social codes).

Common pitfalls

• Building for 10 years before writing a scene: you never get to the story.
• Worldbuilding that constrains no one: empty map, powers with no cost.
• Chronic Infodumping to amortize the research.
• Internal consistency sacrificed for the coolness of one scene (a "unique" spell that would have solved every other conflict).
• "Exotic" details pasted in with no economic or ecological logic underneath.

Examples

• Tolkien — The Lord of the Rings: linguistic and historical worldbuilding, constructed languages before characters.
• Ursula K. Le Guin — Earthsea: minimal yet structural, the magic rests on the "true name" and nothing else.
• N. K. Jemisin — The Fifth Season: tectonic geology and racial oppression fused into a single system.
• Becky Chambers — The Long Way to a Small Angry Planet: worldbuilding through interspecies social protocols, almost without battle.
• Alain Damasio — La Horde du Contrevent: worldbuilding through wind, which dictates every tech and every caste.
• China Miéville — Perdido Street Station: baroque urban worldbuilding, the black economy of New Crobuzon holds the plot together.
• Pierre Pevel — The Cardinal's Blades: worldbuilding by superposition (17th-century Paris + dragon dynasties).

Writing tips

• Apply the iceberg rule (10/90): 10% of worldbuilding visible in the text, 90% backstage. The reverse drowns the reader in infodump.
• Build at least 5 systems (geography, politics, economy, religion, culture) and make them influence each other: a 1-dimensional world (just magic) sounds cardboard.
• Note "what went wrong" in each system: memorable fictional worlds have precise historical malfunctions, not smooth utopias.
• Check sensory grounding on revision: every scene should contain 2-3 world-specific details (smell, currency, idiom) that exist only in yours.

Revision checklist

• Is each rule introduced actually used to block at least one scene?
• Can the reader predict the cost of a power before being shown it?
• Is there a scene where geography / economy / politics changes a character's decision?
• Are exceptions flagged as exceptions (or do they read as inconsistencies)?
